The contact owns a 2019 Chevrolet Trax. The contact smelled an abnormal burning odor and became aware that the A/C unit failed to operate past level 4. The vehicle was taken to an independent mechanic, who diagnosed that the connector for the A/C unit had failed and needed to be replaced. The independent mechanic became aware that the wire for the A/C unit was burned, causing the A/C unit to malfunction. The A/C resistor, connector, and A/C blower motor were replaced. The contact stated that the resistor and connector had been burned 3 times and needed to be replaced again. The failure persisted, and the A/C unit continued releasing the burning odor.

Had issues with a burning plastic smell when initially turning on blower fan to distribute heat in vehicle for about 8-10 weeks. Had vehicle in for service 3 weeks after issue began. Mileage approximately 48,000 miles. Nothing found by service techs. Paid for oil change and vehicle returned to me. Advisor recommended returning vehicle anytime I smelled the odor however I live 30 minutes from dealership and smell would only last momentarily for approximately 1 minute and smell would dissipate. Yesterday at the 10 week mark of the odor occurring on a daily basis of using the heater blower fan it stopped working leaving no option to get any heat in the vehicle cabin. Took to dealership, they indicated today heater fan was pulling too much amperage and caused other heating components to burn out/ melt. This could have caused a vehicle fire and I was lucky it did not happen. …
Air conditioning compressor failed, took to a GM dealership service center and was informed that the AC compressor failed at a weld joint, most likely due to an improper weld. This happened during the intense heat wave this summer (Tennessee Summer 2022) and my air conditioning failed, causing incredibly hot climate conditions in the car, which I had no substitute that I could drive during 100 degree weather. Symptoms had occurred previously, beginning as soon as I purchased the vehicle (but did not realize it was a symptom until the unit went out.) I smelled a chemical smell anytime the air conditioner was running and just believed it to be a normal occurrence, as well as any time I went a long distance using the ac, it would stop working. …
My touchscreen has been malfunctioning and turning black or has a white haze across the screen. When the screen does this i am not able to use my backup camera as it does not work when this happens. To me it is a safety issue not having the backup camera as i am usually backing out of a place with blind spots and the camera lets me see what is behind my car and a good distance on the side of my car. The infotainment screen has done this to me twice now, once at the end of June 2023 and just on July 8, 2023. I have had issues with the infotainment center before but heard nothing back about it. I took my car to the dealership and showed them the pictures of what is going on with my screen and they said it may need a new touchscreen, my car is only 4yrs old!! I have had issues with this since the 2nd year i owned it and honestly I think it's a Chevy manufacturing problem.
The 2016 through 2024 Chevy Trax all have an issue with the climate control fan resistor. It burns out on a regular basis. Very dangerous because as you can see in the pictures it got very hot. It's a bad design, the heat sink is not adequate to hold the voltage and or the motor is too small or bomdined. It's a serious issue that almost every Chevy Trax owner is experiencing. Please we really need your help to investigate this. My daughters drives this car and I need it to be safe. We only owned the car a month before this happened and someone already changed the fan motor and resistor before we got it. Thank you [redacted]
Our problem is with the blower motor not working. There is service bulletin released from Chevy MC-10155050-9999 There is an issue with temperature control cable causing some kind of electrical issue with the fan temperature speed setting. The fan does not operate causing fogginess onto pure on our windshield and unable to operate the car without having driving visibility issues. Which can cause an accident or worse death. Please can you look into this? Thank you [redacted]
I turned on the vehicle and the check engine light came on BLINKING* for the first time. The traction control light also came on after a few minutes of driving. About a minute later, the vehicle began to slow from 40 to a near-complete stop in the middle of a busy road. No blinking lights or alerts. I pulled the vehicle into a parking lot and parked. The vehicle began shaking slightly. I turned off the vehicle for about 15 minutes or so and was able to drive back home with the check engine light still on. I called to have the vehicle towed to a dealership.
